Typo at Jupyter Notebook CERGAS/Notebooks/Italy_mortality_rates_correlations_Time.ipynb

There is a typing mistake (a syntax mistake to be precise) in the Jupyter Notebook at CERGAS/Notebooks/Italy_mortality_rates_correlations_Time.ipynb in the Markdown.

**Original**
```
# Circular Health Project
## Mortality Rate Analysis in Italy (2015-2020)
This notebook uses the mortality rates data file from a subset of municipalities in the ANPR system
and the municipality census information to produce a set of customizable plots
```

**Correction**
```

and the municipality census information to produce a set of customizable plots
```
Although a simple error, but a notebook looks neat and well managed without common errors.
Thanks in advance!
